DANIEL F. PROSSER, OF JAOKSBOROUGH, TEXAS, ASSIGNOR OF ONE-HALF TO WILLIAM L. GARVIN AND JEFFERSON W. MORTON, OF SAME PLACE.

FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 517,394, dated March 27, 1894.

Application filed July 19. 1893.

To all whom i6 may concern;

Be it known that I, DANIEL F. PROSSER, of Jacksborough, in the county of Jack and State of Texas, have invented certain new and useful Improvements in Fire-Extinguishers; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in fire extinguishers; and it consists in the novel means hereinafter fully described for relieving water or steam, or both, into pipes from which it discharges at diflerent points in a building.

The object of my invention is to provide an llnproved automatically operating mechanism for discharging water and steam in a burning building, the same being more especially designed for use in gin houses, although being adapted for use in buildings of every descripion.

Referring to the accompanying drawings: Figure 1, is avertical sectional view of a building having my improved extinguishing mechanism in position therein. Fig. 2, is an enlarged sectional view of one of the explosivev tubes.

A designates the building having a steam boiler B suitably mounted therein for the purpose of supplying heat or power and arranged adjacent the same is the pipe 0 having its upper end D turned over and in communication with the upper side of the boiler, while its lower end is correspondingly turned and in communication withthe bottom of the boiler. Leading to pipe 0 is a water supply pipe E in communication with a force pump or other similar injecting mechanism, not shown. Extending upward from the angle B at the upper end of pipe 0 is the discharge pipe F which may be extended outward into the building in any desired manner and provided with any number of communicating branches having discharges similar to the flexible tube G at the end of said pipe F. Arranged upon the pipe F- is the valve operating rod H carrying weight I as shown, and connected to this weightis the upwardly extending line J which Serial No. 480,935. (No model.)

leads over a pulley K, suitably journaled in the building and outward therefrom in any desired direction where it would be subjected to the flames in case a fire should occur. This ,line is preferably made of stout cord orv any other inflammable material and arranged between its ends are a number of glass explosive tubes L having their ends reduced as shown at L, where the ends of the line sections are secured thereto. These tubes are filled with an explosive compound and projeoting from their ends are the fuses M which depend therefrom in an exposed position. With this arrangement should a fire occur one or more of these fuses will become ignited, thus exploding the tube and breaking the line J allowing the weight I and arm J to drop, thus opening the valve operated by the latter and permitting the steam from the boiler together with water under pressure from the pipe O to discharge through pipe F as will be readily understood. A cut off N is arranged in the pipe section D, so that the steam may be cut off from the boiler and the discharge limited to the water under pressure passing through pipe 0. I also provide the pipe 0 with cut-off M so that the water supply may be cut off and limited to steam. In the latter event a cut off M on pipe E permits the passage of water to the boiler, when required. At all other times the cut off M remains closed, so that the water passing through pipe E and O is at all times ready for the discharge F provided cut off M is open. I prefer however, to so arrange the several cut offs that steam rushing outward through pipe D from the boiler into pipe F will draw with it water up through pipe C, thus discharging the same together as will be readily understood. The upper portion of pipe F is provided with a cut off N andimmediately beneath the same is the hose joint N, to which the hose may be secured if it is found necessary. Arms H also support a smaller weightP and connected thereto is line P leading to a whistle Q, so that in case the extinguisher is set in operation an alarm is sounded for the purpose of attracting attention.

The extinguishing mechanismherein shown and described is especially adapted for use in gin houses where fire is liable to occur at any time, and in which places it is very difiicult to control. The fuses projectingtrom the explosive tubes being very sensitive are soon ignited and the extinguishing fluid thereby applied almost instantly through the several discharges provided for it.

The extinguishing mechanism is however well adapted for use in other kinds of build ings and its operation will be equally as effectual. The line J being within convenient reach may be broken by hand if so desired, and the same thus set in operation if the tire is discovered before the mechanism is set in motion automatically.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. An improved lire extinguisher comprising a steam boiler, pipes 0 adjacent the same, branch D connecting said pipe with the top of the boiler, branch E connecting the lower end of the pipe with the lower portion of the boiler, a discharge pipe leading from the angle of pipes C and D, a water supply in connection with pipe 0, a valve in pipe F, and a means for operating the same, substantially as shown and described.

2. An improved fire extinguisher comprising a steam boiler, pipe C adjacent the same, cut off M therein, branch D connecting said pipe with the upper portion of the boiler,cut off N in said branch, branch E connecting the low or portion of said pipe with the lower portion of the boiler, cut off it" in said last named branch, water supply pipe E in communica tion with said pipes D and E, discharge pipe F leading from the angle between pipes C and D, a valve in said pipe, and a means for operating the same, substantially as shown and described.

3. An improved fire extinguisher comprising a reservoir, a discharge pipe therefor, a valve in the pipe, a line for operating the valve, said line being in sections, explosive containing tubes arranged between the ends of the sections, and having reduced extremities to which said line sections are secured, and fuses projecting from the tubes, substantially as shown and described.

4:- An improved fire extinguisher comprising a fluid extinguisher and means for confining the same under pressure, a discharge pipe, a valve and a weighted arm for operating the valve, aline for supporting the weighted arm, tubes in the length of the line having reduced necks, explosive materials within the tubes, and fuses projecting from the tube ends, substantially as shown and described.

In testimony whereof Iaftix my signature in presence of two witnesses.

DANIEL F. PROSSER.
